; This invention relates to safety; razors employing replaceable blades and consists in' an applianceA which includes `a receptacle `for used` blades and means for transferring into the receptacle used blades one at aitime from a razor presented in a predeterminedposition adja` cent to the blade receptacle.

Much attention has been paid to the provision of magazines for supplying fresh sharp blades to safety razors but littlev attention has been paid heretofore tothe problem of expeditiously, cleanly and safely,removingusedblades from safety razors and at the same time disposing of them so as to eliminate the `menace of loose used blades. Under the best conditions the user will remove a usedblade `from his razor after each shaving operation, carefully clean `and dry both the blade and razor `and= returnv the blade to its shaving position in therazor in preparation for subsequent use. :It frequently happens, however, that, on'account of careless.

habits or press of time' a used blade may be left without cleaning in the safety razor for several days and thus accumulates rustand dried debris which interferes with the Vfree removal of the blade. The user is then extremely likely to cut his iingers in forcibly removing such reluctantblades. i

An obiect of the present invention aims to obviate this danger by providing for "the "quick andsafe removal efa used blade from the safety razor and its immediae delivery into a blade receptacle of substantial capacityl? With tl'ieseA ends in View an important feature o'fimy inven-` tion consistsin thecombinationof 'afblade re-u ceptaclewith razor 'supportingmeans adjacent thereto and adeviceforftransferring the blade i from a razor presented onthe supporting means and into` the blade receptacle, all in a single yfolperation or in related and progressive steps. u

Fig. ,4: is a view in front elevation of a modi-` type of safetyrazor or .bladebut with appropri-` ate `rriodii-lcation may be adapted for any type of` safety. razon employing` removable interchangeable .blades As shown in Fig. 1 the appliance has an elongated rectangular bodyv Il! which may be moldedges of the guard n2S of a safety razor. Between an important feature of my invention e ediroml plastic material or fabricated of wood or light metal. The bodyv I0 is hollow and its left-,hand end as herein shown is shaped to provide amblade` receptacle which is enclosed by a cover `II lmounted on a pintle I2 to swing on a *horiaontaljtransverse axis and having at its free gend a downturned transverse flange I3. Spacedbelow the flange I3 by asufcient distance to provide a, blade inlet slot I4 is a statif'nnary;M transverse wall I5. A pair of long itudi` nal shoulders or ribs I6 is located `in spaced, relation vkupon` the inner side walls ofthe appliance below its upper surface and in position to engage and support the parallelflongitudinal the ribs IIS provided a curved longitudinal partition I8 which, with the` ribs, defines `a trougl'A providing clearance space in which the cap 21* of a safety razor may be freely suspended when :the razor issuppo-rted with the edges ofitsl guard upon the ribs I5, `The space be-` neath thejlongitudinal partition I8 is utilizedvas an extension or addition to the blade receptacle spect to the blade receptacle and the blade inlet slot M. f

`The blade-ejecting` device as shown in Figs..

tudinal partition IS and projects upwardly so.

thatits upper end is located substantially opposite to a blade lying between the'cap and guard' of a safety razor when the latter is properly presented to the appliance. Iif desiredv they wallsof the appliance may be designed to include-A a, pair of longitudinal pockets 2| and 22` for -the reception of packages: of' unused blades are thus maintained asf a convenient' supplyl where they are readily accessible to thefuserzf rIlhe safety razor herein-'shown comprises ani elongated guard 26, a `cap- ZT' having ani-nner concave blade-shaping face and"` being carried by the end ofa spindle 2'81.' Thisfspindle is-I t'ele'-L scop'ically received within the handle ofthe razor and surrounded by a compression spring 29 tend-i inggat all times to moverthe spindle and cap upwardly, in Fig. 31, into bladeeengaging,positicna Thehandle is closedfby a cylindrical nut 393 through which the spindle` Z may b evmovedl longitudinally in to blade-releasing ,positionv by longitudinal' movement or the nut crmovedinto blade-clamping position by rotation of thel nutthrough a threaded connection (not shownj). The razor herein described is disclosedSY in more detail inrmy co-pending ap'plieation,y Serial'Num# ber 488,571', filed May 26,1943'. "`In using this razor the cap may be temporarily separated from the guard by endwise pressure uponthe nut 3l) and a free passage thus' provided'forthe' insertion of a blade, withj'or without au.protectiveV cover.

therazlor, however, the. nut :id may be depressed. by the. user against thef pressure ofthe springnlflY tosome such. position. as that shown@ in-Fig.- 3 in` which. the blade is substantially released and permitted to assume iiat condition. In this flat.

Aposition it is located at the. same level and in` alignment. with the slot ld. The spring llis now deflected outwardly andA then released. so. that it. snaps inwardly at, its, upper end striking the right-hand end ofY the blade.A with sharp impact, andz driving or kicking it. toward. the left out` of the razor through the-slot i4. and into the.` blade receptacle. beneath. the cdver: l. t, 1-he impact, of

, spindle. fremd-positive.'

the spring I9 is suicient to loosen the blade from any adherence either to the cap or guard caused by accumulated debris in the razor. It will be noted, moreover, that the lower face of the guard is so located that even if the blade sticks thereon it may still' be transferred directly from the safety razor to the blade receptacle. The appliance is of such size and the receptacle of such dimensions that it will hold a substantial number of used blades, for example, a years accumulation. At the end of that time the cover H may be raised and the used blade permanently disposed ofi.

Instead of tensioning and releasing the ejecting spring. I9. by handl mechanical means may be provided, desired, for that purpose. Such `mechanism is illustrated in Figs. 4 and 5 in which thecurvedleaf! spring 33 is secured as before to ther end face of the appliance but in this instance it is provided with a vertical slot designed to receivea portion of aspiral'. cam 341 mounted on a transverse shaft 35 which is journalled in bearing lugs 36 and: provided at its outer end with an operating' head 38.. When this is rotated the cam 3.1: forces the spring 332 outwardly under increasing tension. until a drop off point is reached in the periphery of the cam. When this drop off' point passes the edge of the slot in the spring the spring isfreleased. and allowed to snap inwardly to engageand eject a blade 3l in the manner already' explained.
